Wanneer er geen disk in de speler zit falen sommige routines. De

exceptie heeft nu in dat geval als argument "no disc in player", behalve
wanneer de bibliotheek routine errno zet.  In dat laatste geval wordt
(nog steeds) err_errno() gebruikt.

Wanneer een routine uit de bibliotheek faalt wordt nu altijd een IOError
gegenereerd.  Een RuntimeError treedt alleen op bij verkeerde argumenten.
